    Default Which of these Chieftec-s are CWT? (need new budget PSU)

    Hello,

    I currently have a gps-450AA-101A Chieftec which is made by Delta and has 29A on 12V dual rails combined, I have heard it is a quality unit but I think its not enough for my new setup:

    Specs:

    3750K
    GA-Z77-D3H
    2x 4GB Kingston HyperX 1866MHz DDR3
    1x Samsung EVO 250GB SSD
    1x Seagate Sata II HDD 320GB
    Gigabyte Windforce 280X 3GB OC

    My budget is low and for my budget there are only available semi-quality Chieftec PSUs. I have heard alot of them are made by CWT so I want to ask someone smarter than me to point out which one should I buy.

    1) Chieftec GPS-500A8 500W PSU 12CM FAN ACTIVE PFC ATX12V V2.3 80+ EFFICIENCY (WITH POWER CORD)

    2) Chieftec GPA-500S8 500W 12CM ATX2.3 80PLUS

    3) Chieftec PSU 500W GPA-500B8 85+ 500W, Active PFC, 120mm,,3xSATA,2xATA,1xPCI e(6+2-pin),1x8pin CPU,120mm fan

    4) Chieftec CTG-550-80P 550W

    5) Chieftec CTG-500-80P 500W Oem

    6) Chieftec GPS-600A8 600W 12CM FAN ACTIVE PFC ATX12V V2.3 80+ EFFICIENCY (WITH POWER CORD)

    7) Chieftec CTG-550C 550W 85+ Modular, v.2.3, 85+ , Active PFC, 2x PCI-E (6+2-Pin), 6x SATA, 4x MOLEX, Fan 12cm, w/cable Management

    8) Chieftec CTG-600-80P 600W

    9) Chieftec PSU 650W Chief CTG-650-80P

    10) Chieftec PSU 700W GPS-700A8 700W, 85+,6xSATA,4xATA,2xPCIe(6 -pin),1x8pin CPU,120mm fan

    So I would like to know from the smarter people, which one of these are CWT made because I have heard Sirtec is to be steered clear from. Also I have a question, can I run my setup on the original Delta made Chieftec for a short period of time until I get new PSU if I dont run any synthetic benchmarks and I dont overclock. With new PSU I want to get the 3570 running over 4.2GHz and OC the GPU a little bit too. Thanks people.

    If you are asking why Chieftec, then because its the only semi quality brand (if CWT made) that fits into my price range with wattage enough to run the 280x.

    3) Chieftec PSU 500W GPA-500B8
    6) Chieftec GPS-600A8 600W
    10) Chieftec PSU 700W GPS-700A8 700W

    Sirfa High Power Element:

    5) Chieftec CTG-500-80P 500W

    Sirfa High Power Absolute:

    4) Chieftec CTG-550-80P 550W
    8) Chieftec CTG-600-80P 600W

    Sirfa High Power Element Smart:

    9) Chieftec PSU 650W Chief CTG-650-80P

    Sirfa High Power Direct12 Bronze B14C:

    7) Chieftec CTG-550C 550W


    Both Sirfa(/Sirtec) and CWT have many different designs of varying quality, whoever told you that anything from Sirfa is bad isn't quite right.
    Instead of listing Chieftec PSUs available to you, how about you just link to an online shop that you can buy from?

    Today, it's called a low-end Delta PSU, based on a double forward design with group regulation, Ltec caps, a Yate Loon sleeve bearing fan and only one 6 PEG connector.

    It never was a high-end PSU, back in the day it was a nice budget PSU.

    but I think its not enough for my new setup:

    Specs:

    3750K
    GA-Z77-D3H
    2x 4GB Kingston HyperX 1866MHz DDR3
    1x Samsung EVO 250GB SSD
    1x Seagate Sata II HDD 320GB
    Gigabyte Windforce 280X 3GB OC
    It's probably smarter to get something new yeah.
    So I would like to know from the smarter people, which one of these are CWT made because I have heard Sirtec is to be steered clear from.
    You have heard wrong, Sirtec and CWT can be pretty close, they even outsourcing things to each other. CWT and Sirtec both sell low-end to high-end stuff. Delta also sells low-end to high-end stuff, the thing with low-end Delta stuff is that the lay-out is really thought out, and the solder work is always great. But that doesn't mean a low-end Delta PSU is better then a mainstream PSU from Sirtec or CWT.

    Also I have a question, can I run my setup on the original Delta made Chieftec for a short period of time until I get new PSU if I dont run any synthetic benchmarks and I dont overclock.
    Just barely and you need double molex to PEG connector.
    If you are asking why Chieftec, then because its the only semi quality brand (if CWT made) that fits into my price range with wattage enough to run the 280x.
    Do you buy from a web shop?

    Corsair VS450 would be fine if you're on a budget; it doesn't quite fit a setup with a high end card like the R9 280X, but it will work.
    There's also Cooler Master B500 v.2 for not much more - same thing as the Corsair, but 50W more. They both have two PCIe connectors.

    Cooler Master G450M is a much better unit than the other two, includes DC-DC converters, modular cables, and 5 year warranty.

    If I have a chance to grab a used Nexus NX-5000 R3
    530W, 41A 12V for 40EUR, should I go for that instead?

    That one is close to the Chieftec CTG-550C. The Chieftec and Nexus are both using a double forward design with indy regulation and Teapo caps. The Chieftec is only a Sirtec and the Nexus an ATNG. Performance and quality wise they should be close.

    But because the Chieftec is new and modular and the price is actually quite close with 40 and 47,90 euro, I would get the Chieftec.

    The only other new PSU you should consider is the Cooler Master G450M, the others are just to low-end in my opinion. But I prefer the Chieftec over the Cooler Master in this case.

    I've owned it: it's a nice and quiet PSU, but it's used, and given that it's in the wild since a rather long time, IMO you should at least know for sure how old it is and how hard it worked since then.

    I'm saying so because AFAIK Nexus units are well regarded for quietness, not for either build quality or reliability.

    Personally, unless silence is paramount, I wouldn't recommend to buy such a used PSU.
    Best, Luca
