Upgrade PSU to 500W on the p6-2340ea

[MikeR1]

I have purchased a Zotac  GeForce GTX750Ti 2GB single fan Graphics Card that takes its power directly from its slot on the motherboard..Whilst I have been told that it will function OK on my existing 300W PSU I am thinking about purchasing a 500W PSU as a replacement, just to be on the safe side.

The PSU I have in mind is the:-

SUMVISION ATX PC POWER SUPPLY UNIT QUIET / SILENT PSU 500W WITH SATA

500 Watts
4 x SATA Connectors
Motherboard connector : 1 x 4 pin
20+4 pin connector ~ suitable for both 20 and 24 pin motherboards
1 x 4 pin Floppy Drive connector
1 x Molex Connector (for IDE drives)
Operating Life ~ 115 Vac Operation 230 Vac Operation
Model ~ Power X3
AC input 230V, 50-60Hz
Complies with FCC Part 15 Class B and CISPR22
RoHS Compliant

My question is... a) would this be a good choice...and b) is it compatable with my system

Your comments and expert guidance wouild be appreciated.

A. No. I doubt it can even deliver 200W safely and with terrible efficiency at that. Same with Logisys, Athena Power, and other cheap brands. I suggest an EVGA 500B unit as it is much safer and can actually deliver its rated wattage. 

B. Yes, it would work, if it doesn't blow up your PC while doing so.

Many Thanks for the warning...that will teach me not to look for the cheapest (apparent) solution...Will go see the EVGA one you suggest.

Hi again...Have received a very good offer on a boxed brand new EVGA 500W...some £20 less than quotes for the 500B

Will this do equally as well for my set up?

I don't like the standard 80+ EVGA PSUs as the B1s are already pretty cheap. The power supply should be the thing you attempt to spend the most money on in a PC.

Again...many thanks...the 'B' version it will be.
