Should I buy this PSU?

[lawrence281]

I've got a gtx 1070 coming, and run a i7 4790k.

And this dude is selling this PSU for £60 collected.
Corsair CX750M 750W ATX 80 Bronze PC Power Supply Black 120mm Fan Protection PSU

Yay or nay? Should I negotiate down a bit more ?
(Sorry copy paste made this text like this )

Definitely not. You don't need 750w for that hardware, and you can find better (brand new) PSU's for less money


Corsair CX550M 550 W 80+ Bronze (semi-modular, 5 year warranty)

Super Flower Platinum King 550W 80 Plus Platinum (non-modular, 5 year warranty, but higher efficiency).



For pretty high-end hardware, I wouldn't ever risk it on a second-hand PSU.

Also, assuming it's the old version of the CX750M I would definitely avoid anyway due to its low-spec design.

Thanks for the reply, you're completely right. I might go for the super flower. But is it enough if I decide to overclock the gpu a bit if I need to? Don't think I'll need to do cpu. Seems pointless for me

Yeah, you'll have plenty of overhead. You could even run a GTX 1080 easily.

To give you an idea of how little power you'll use, another user with a similar PC recently said:

I would just make sure that the Superflower PSU I linked has all the connectors you'll need, as it isn't modular or semi-modular. There are other similarly priced options available, but not on Overclockers. So if you really wanted modular/semi-modular you'd have to shop around.

I think the psu you linked is absolutely fine, should work. Kinda wanted modular for airflow and make it look neater. But money wise it's not really that much worth it is it
