Corsair TX650 - Change in specs and OEM?

[Smirnoff]

Dunno if this has been mentioned earlier, but Ì was looking at the Newegg page for the TX650, and noticed the unit looked somewhat different (having owned that model, I don't remember it looking the way it does now). Also, on the picture of the label, the 12V rail now has 53A (636W) available, contra the 52A (624W) from earlier. The fan looks like a 140mm, instead of the normal 120mm one. The model designation also reads CMPSU-650TX-C. Has it silently been swapped for a CWT model?

yes, looks like the 5Vsb also upgrade from 2.5A to 3A

It's a PSHII650.

sorry my wrong the 5Vsb didn't change
but Corsair still keep the old version (52A) with small fan (120mm) on their website

I guess the -C version is OEM from CWT and I just find the PSHII have the same rating

Do you know the difference between PSH and PSHII?
Did PSHII outperform old PSH or not?
Looks like 750/850TX still the old PSH since it without -C on the model name

Too bad we didn't review the original TX650. I would've loved to do a side by side comparison of the performance.

It's a pitty not to have another two PCIe connectors more in the new model. 650W is power enough to handle two graphic cards like the GTX460 in SLI. We will have to continue using molex-to-PCIe adapters...

It uses single-layer PCB and layout is different too. It's just a cheaper PSH though the original PSH was quite cheap for its quality.
From the Chieftec Nitro review by theLab.gr, I think its ripple is a bit lower than the original PSH.

If you need an original version to test I think I can accommodate you, Jon. I have one in my main system that I could replace with a psu I have sitting that I bought off O_W at OCF.
