Diff in psu?

I was told by mrcrusty that brand name psu's are more reliable. He recommended this psu http://www.newegg.com/Product/Produc...82E16817371021
However, now that I'm tight for cash every few dollars counts. I found 2 a similar psu for a slightly lower price. Could you tell me if these 2 are very similar and will both do the same job as the first. http://www.newegg.com/Product/Produc...82E16817371015

I need it to run an oc'd Radeon 6870.

Thanks.

You'll be fine. I use a Neo Eco 620w for my own PC. I think it's a revision of Seasonic's S12II PSU. Has the same design, but uses lower quality Taiwanese capacitors on the secondary side instead of the much advertised "100% Japanese capacitors" and has slightly less efficiency. Or the other way around, Seasonic's M/S12II PSUs are a revision 2. of the Neo Eco. The Neo Ecos came out first and Seasonic probably decided to make a few changes to improve the unit before theirs went to retail. In either case, it's got the guts of a high quality Seasonic.

The EarthWatts is good too, comparable to the Corsair TX (though it has less efficiency).

XFX Core Edition Pro 650w and Corsair TX 650 should also be taken into consideration. Similar price, similar performance.

A 650w PSU is actually a little on the heavy side for a single 6870 if you don't plan to overclock the CPU that much, even with an OC on the card. You'd probably scrape through fine with a good 550w PSU. A 6870 consumes around as much power as a 5850, more with an overclock, but I know you can run two 5850s easily with a quality 650w.

Is the brand Rosewill reliable? And how are these psu's for an oc'd 5870?

**Ishan** · December 18, 2010, 03:00 AM

Rosewill has a poor history of offering powersupplies of questionable quality and value.
They do make a few that are adequate and a few that are better but overall their quality is inconsistent so not worth it imo.

Alright.

Oy. I got it. Will these two be sufficient for each other(and and average system)?
