I'm planning on upgrading my PC wondering if my current Antek power supply will be enough to power a Asus P5K-V and a Core 2 Duo.

My system configuration will look like:
-Asus P5k-V w/ a intel Core 2 Duo 2.4ghz
-I'll be using mobo's onboard video
-2gb RAM
-320gb Segate SATA HD
-160gb Maxtor IDE
-LG 16x DVDR
-3.25" FDD
-1x120mm 800CFM casefan
-I only have 1 USB powered device

My case is a Antec SLK3700AMB http://www.antec.com/us/productDetails.php?ProdID=93700#
with the factory Antec SL350 power supply.
specs at http://www.antec.com/specs/sl350_spe.html

Will this power supply be good enough for what I need?
I know a lot of powersupplies might be rated for 500w but are actually crap.
I'm hoping that my Antec will do the job and do it well.

Your system as described requires ~198W - http://www.extreme.outervision.com/PSUEngine. Just select your components for your system and click calculate.
 


Your current psu has 16A on the 12v rail and you are using onboard graphics. You can give it a try with your processor upgrade and beware of any unexpected system shutdowns or crashes. You might want to upgrade your PSU now to a unit with more power on the 12V. Should you plan to add a video card to the system in the future, you will will need a PSU upgrade. HTH.

I wouldn't trust a low wattage power supply that came with a case, even if it is by Antec. It looks to be one of their very cheap lines of power supplies, so I would recommend getting something new. An Antec Earthwatts 380W is highly efficient(80+ Certified) and should be fine for what you have. The general rule with included power supplies with cases is just avoid them.

upon further research the Antec SL350 power supply has a 20 pin ATX connector and the Asus P5K-V mobo I'm looking requires a 24 pin ATX power connector.
It looks like I'll have to buy a new PS anyway.

Maybe I'll just buy a Antec Sonata III with a EarthWatt 500 psu

I just saw this post looking for information regarding underpowered PC's. But, I've used the following setup for years just fine:
- Case: Antec SLK 3700 (with a 12cm FAN)
- PSU: Antec TruePower 350
- Mobo: Intel DP965LT
- CPU: Intel Core2 E6300 (6 months), Intel Pentium D915 (Dual core @ 2,8GHz, 65nm: 18 months)
- VGA: Gigabyte Radeon X1600XT
- 2 x hard disk @ 7200RPM
- 1 x DVD-RW Drive
Before this configuration(s), I ve "underpowered" an ATI Radeon 9800Pro, which "needed" "at least 400 watt PSU. Overall, that PSU has been used for about four years by now, and it still performs very well.

Now I want to know, if anyone can tell me, what to expect from a possible underpowered PC, with this setup:
Case: Antec NSK 1300, with 300 Watt PSU
Mobo: Intel DG965OT (G965 chipset, ICH8DH)
CPU: Intel Core2 Duo E6300
VGA: Radeon HD 3870
1 HDD, 1 DVD, 2 USB devices
At this time, this configuration does not suddenly shut down, as I might expected.

If it is stable now, don't expect it to stay stable with an OC/any further OC'ing than you might be doing now. I am running and E8400, XFX 780i, and an 8800GT from PNY self OC'd. All with a 400w Ultra modular. Much overclocking on the CPU will cause crashing. And I cannot get it stable over 3.6, which is possible on all levels, thus being the PSU, I'll try to post my results after I get my 750TX from Corsair.
