Guys (or more appropriately girls),
Can I please ask why we are suggesting upping the wattage?
The PSU he had was presumably adequate for "a" length of time and providing this length of time was reasonable there is no reason he needs to up the wattage.
Delong doesn't sound like a brand any of us recognise so that generally (but not always) means a cheap brand with not great efficiency so if he goes for a 375 Watt by a trusted recognised brand there is NO reason to up the wattage and potentially increase the price.
For all we know this PSU has come out of a small i3 machine with 1 stick of RAM, 1 HDD, 1 DVD drive, no additional graphics or sound or any other cards meaning the wattage required could be as low as 150.
Sorry Girls, I know this is a lengthy post but it isn't a rant, or a dig at you it's just I think we should find out the spec of the machine this is going into before recommend he up the wattage?
So . . . . . . after all that, can you let us know the specification or make / model of your PC?
(It's now going to probably turn out to be a high end gaming machine sucking 500 Watts of power, making me look silly
)
