Power Supply Configuration for SLI Support

wescrock · Sep 10, 2015

Hello,

I have a Solidgear 650E PSU (http://www.amazon.com/Solid-Gear-ATX12V-650-Watts-SDGR-650E/dp/B00A8ZZUXO) and am wondering what the best option is for SLI support. It only has a single 6 pin (+2) for PCI-e. Should I buy a dual SATA to 6-pin or a dual MOLEX to 6-pin?

It will be driving two GTX 650 ti Boost's, so the 650W PSU should be sufficient in that regard.

Thank you,
Wes

I do not trust that power supply to deliver the full 650 watts, I think that is a tier 4 or 5 PSU as a result a Molex to six pin or sata to six pin is a bad idea.

Quality is everything. Adapters are a bad idea. Get a proper power supply of better quality that has the correct cables to do the job. A 650 watt PSU with only a single 6-pin is not a good PSU.

Agreed with Robert. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html That thing will not give the full 650W and Molex to 6pin/8pins are always a bad idea. Its not even on the PSU tier list so its definitly a tier 5

see that red slider switch on the back, beside the power cord input and power switch? red switch = red flag. old old cheap cheap design. stay away. and definitely not worth $45!!!

i'd MUCH sooner buy an EVGA 500B than that thing.

well it does mean old, but my 1995 power supply is not cheap at all....

I have an AMD FX-8350 on a Gigabyte UD3 motherboard. 8gb RAM, 1TB HDD, 256GB SSD. What wattage is needed to drive all this with 2 GTX 650 ti Boosts? I may be able to swing for another PSU.

that was then. this is now. if a company is too cheap to use a modern APFC circuit, what else are they too cheap to include?

ajhockey3 · Sep 10, 2015

I would say probably an 600-750 of a GOOD quality power supply. Running SLI eats a good amount of power. Buy something good like XFX or EVGA. But don't buy a CX series from corsair. Alot of people do that

Archaic59 · Sep 10, 2015

650 watts from a high quality power supply. If you plan to overclock the cpu / gpu's a 750 would be better.

wescrock :

[strike]can you go from $45 up to $49 or so? i mean, it's only four bucks. less than a cheeseburger.

oh, wait. FX processor? 500B would be cutting it too close.

yeah, 750 would be good. my bad!

Robert Cook · Sep 10, 2015

as said above I would go for 750 for the headroom. it is always good to have headroom...

wescrock · Sep 10, 2015

Because I already own the PSU. I am upgrading my system, hence the older parts.

Robert Cook :

Could you return it? Before your blow your system or burn your house down with such a sketchy psu

ajhockey3 · Sep 10, 2015

Also read the amazon reviews. It sounds awful

Robert Cook · Sep 10, 2015

^^^^^^^ electrical fires are nasty, avoid them at all costs.

wescrock · Sep 10, 2015

I realize the poor reviews. It came as a bare bones bundle that I purchased and I was leery of it then too. That being said, I have had 0 issues with it thus far. I can't spend $80+ on a new power supply, but might be able to justify 60 or so. If someone gives a decent recommendation, I may be able to pursue it.

ajhockey3 · Sep 10, 2015

Also when you work in the computer industry for so many years.... the smell of electrical fire is just...awful

giantbucket · Sep 10, 2015

where do you shop?

ajhockey3 · Sep 10, 2015

Also just a tip. Your running SLI. Its good to get an SLI certified PSU

wescrock · Sep 10, 2015

doesn't matter where it is from, best price always gets my credit card.

giantbucket · Sep 10, 2015

US? UK? Canada? Australia? Fiji?

wescrock · Sep 10, 2015

US.

How is this? http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=9730711&CatId=2533

Looks good, Tier two I think its seasonic design

giantbucket · Sep 10, 2015

nobody will say that the EVGA 750 B2 is a bad unit. $80 after rebate, free shipping

http://www.newegg.com/Product/Product.aspx?Item=N82E16817438028&cm_re=evga_750b2-_-17-438-028-_-Product

it's just one option.

i've always been curious about this specific Thermaltake as well: http://www.newegg.com/Product/Product.aspx?Item=N82E16817153198
