    Default Need suggestions for a 750 watt PS around $80 w/molex

    Gents,

    I'm looking at replacing a rock solid 9 year old Rosewill PSU for around $80 but I've run into a snag trying to find one. I'm looking at modular/semimodular units and it seams many do not have any molex connectors. I hate to cut up the cables and make my own but I may have no options.

    The molex connectors are needed for a Modded PC that contains cold cathodes, Areocool fan/temp controls, and lighted side fan grates.

    Any suggestions on a PSU with those options that Jonny has reviewed and is in that $80 (prefer less) price range?

    **Note** Wattage calculate at 480-554 watts with 20 watts overhead for lights and extras so has to be over 600 watt or higher.

    What are your reasons for not just buying some SATA-to-molex converters?

    Because SATA connectors suck would be enough.

    You dont need a quarter of that power.

    Get a proper 400-550 unit. That would be plenty for your system and even upgrades (i5-i7 / GTX 1060 / GTX 1070...etc).

    You can use Molex to sata adapters / sata to molex if you are short on cables.

    This PC only takes around 250W tops out of the PSU under gaming load, no way near the 480-554 watts. With a high quality 600W PSU you can easily power three of your graphics cards, even four should be possible.

    So a 350W/400W PSU with one PEG connector and enough sata connectors should be the best option, sadly those power supplies almost don't exist, especially in the USA. So you're probably should stick with something that can easily power two GTX 960's like the Corsair CX450M and buy an extra modular sata cable.

    Can you point me to a review by Jonny? Saw the post started by "Orion" in Feb. I'm having a hard time coming to grip that I can use a 450watt PSU and send all my power down those 4 connectors to the PSU and using that SATA adapter for splitting power as it has to reach forward (bottom) and backside (top) of case as HD's are located on each side top/bottom.

    *Note* Still won't help my lack of molex connectors with limited connection points.

    Great price though!!

    Nope, doesn't exists.

    There is a Vengeance 650W review from Jeremy, difference are of course less watts, but other differences are single rail and different capacitors, otherwise they should be the same.

    Don't, 450W is overkill and not meant for a PC with GTX 960. There is a reason that the CX450M (and all decent 450W PSU's) have two PEG connectors and the GTX 960 only requires one. A GTX 960 only takes 125W.

    and send all my power down those 4 connectors to the PSU and using that SATA adapter for splitting power as it has to reach forward (bottom) and backside (top) of case as HD's are located on each side top/bottom.

    How many sata and molex connectors do you need?
    If you need more molex connectors buy an extra modular molex cable.

    @Microbell: unfortunately overestimation and crappy PSU calculators have poisoned the minds of the youth on the true power requirements. People for some reason can't get a grip on the idea that buying a PSU to "have more power" is more some mythical fairy tale state of mind that gives it peace rather than a realistic thing, since a PSU is not some kind of enlarged juice box with power inside.

    I know it can be shocking coming to this site because on other sites everyone over-tecommends in general. But this site is filled with PSU experts and reviewers from around the world (not me) so you can count on the advise they give being solid and on real information.
